func (*Container) Import ¶

func (c *Container) Import(module Module)

Import can be used to combine multiple modules into one.

func (*Container) Register ¶

func (c *Container) Register(provider interface{}, as ...interface{})

Register teaches container how to create an instance of the given type, for instance:

container.Register(
    // tell the container how to create an instance of *MyType
    func() *MyType { return &MyType{} },
)

container.Register(
    // tell the container how to create an instance of *MyOtherType from *MyType
    func(*MyType) *MyOtherType { ... },
    // second argument registers *MyOtherType as MyOtherTypeInterface too.
    new(MyOtherTypeInterface),
)

Register also registers resolvers for pointers to the type, so circular dependencies are possible:

container.Register(func(*MyOtherType) MyType { ... })
container.Register(func(*MyType) MyOtherTypeType { ... })
